Three Must-Try Guitar Wiring Mods

Instead, let’s look at an approach that uses mini-switches rather than a big rotary switch. These limit you to three settings per switch, as opposed to as many as a dozen from a rotary switch. But there are at least two good reasons to go this route: It’s easy to install mini-switches on almost any guitar, while adding pots can be problematic. And there are times when you might want to deploy your pots for something other than the traditional uses—controlling onboard effects, for example. (Which, by the way, is the subject of an upcoming Premier Guitar article.)

There are many types of mini-switches, but this project calls for the on/on/on DPDT variety, which have two rows of solder lugs and three switch positions. Diagram 3b shows how they work—and how to configure them as treble-cut and bass-cut controls.

A 3-position treble-cut switch. For a treble-cut switch, connect the input to the left-center lug, and a ground wire to the right-center one, as shown in Photo 3b.

With the switch in the down position, the signal gets routed through whatever you connect to the top two lugs. In Photo 3c I’ve threaded the first of two treble-cut caps—a .022 µF (223)—through the top lugs.
